The short version

  • Each has a real cost: Atlantis there is no company, no service level agreement and no paid support at any price, and the six maintainers are volunteers with day jobs, which some risk committees will not accept for a component holding production cloud credentials.; Honeycomb free tier caps at 20 million events per month and 100 million metrics data points

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Atlantis

  • There is no company, no service level agreement and no paid support at any price, and the six maintainers are volunteers with day jobs, which some risk committees will not accept for a component holding production cloud credentials.
  • The security surface is inherently sharp, because it is an internet-reachable webhook endpoint that executes applies with privileged credentials, gated by pull request comment authorisation that is coarse next to a real policy engine.
  • It is stateful, holding a working directory and lock database on local disk, so high availability and horizontal scaling are awkward and you own upgrades, webhook plumbing, secret rotation and the host itself.
  • It lacks the features that distinguish the commercial alternatives, with no native drift detection, no cost estimation, no managed state interface and no policy engine beyond the Conftest integration.
  • Terragrunt and monorepo layouts are not first-class, requiring hand-written custom workflows and repository configuration that becomes a growing maintenance burden as the number of repositories increases.

Honeycomb

  • Free tier caps at 20 million events per month and 100 million metrics data points
  • Pro tier starts at $150 per month for only 50 million events, with cost scaling per additional event block up to its 750 million event ceiling
  • Enterprise tier's event and data point volumes are variable and its price is custom, requiring direct sales contact
  • Telemetry Pipeline is billed separately at $0.10 per GB on top of the base plan price

No. It runs as a series of LF Projects under the Linux Foundation and is maintained by volunteers. There is no vendor to buy support from and no service level agreement.

Honeycomb: Is Honeycomb free forever?

Honeycomb offers a free plan forever with up to 20M events per month and 100M metrics data points per month, best for testing and individual projects.

Atlantis: Is it a CNCF project?

No. It uses a channel in the CNCF Slack, which is often misread as membership, but the project sits under LF Projects rather than the CNCF.

Honeycomb: What is the cost of Honeycomb's Telemetry Pipeline?

Honeycomb's Telemetry Pipeline starts at $0.10 per GB, with monthly or annual billing options available.

Yes, there is a dedicated integration guide alongside Terraform, and it also has configuration for working with hosted Terraform backends.

Honeycomb: Can I get custom Honeycomb pricing?

Yes, Honeycomb offers Enterprise plans with custom pricing and a base allowance starting at 10 billion events per year with dedicated support.

Source
Atlantis: What does it not do that a paid platform does?

Drift detection, cost estimation, a managed state and run interface, and a real policy engine. Atlantis does pull request plan and apply well and stops there.
